A domestic homicide on Chicago’s South Side claimed the lives of 68-year-old preschool teacher Phyllis R. Goolsby and her 71-year-old sister Tuanna Thomas on the night of March 7, 2026. Goolsby taught four-year-olds at Raycoan Scholastic Academy for 15 years and was described as a beloved member of the school community.

Police were dispatched just before 11 p.m. to Goolsby’s home in the 10400 block of South Peoria after a 911 call from 75-year-old William Wallace Jr., identified as Goolsby’s boyfriend of 25 years, who said he had shot his girlfriend and her sister. Officers found both women with fatal gunshot wounds to the chest; both were pronounced dead at the scene. Wallace was taken into custody at the residence, a weapon was recovered, and he later confessed to the killings. He has been charged with both murders.

If anyone knew Phyllis Goolsby or Tuanna Thomas and can share information about their last movements or the household, please contact investigators.
